Sheet 1 of3 INVENTORS JVeiZ- S. .Wazferman .P/z/zLZi a H-Borcien Patented Dec. 1, 1970 Sheet g 013 DISPENSING PACKAGE coNrAINsR son NEW AND USED nszon BLADES BACKGROUND OF THE INVENTION Because of the widespread use of double edged safety razors, and the extensive repeat order market for such razor blades, competition in the industry has lead to many and varied types of packaging, all designed with a view toward capturing public favor through attractive appearance, lower cost, user convenience or acombination of these factors. The use of molded plastic containers has resulted in lower cost and eye-appealing packages. For the users convenience, many types of dispensing packages have been devised to easily and safely dispense razor blades one at a time. However, because of practical limitations in maintaining close mechanical tolerances molded plastic containers have not proven entirely satisfactory as razor blade dispensers. Attempts at making razor blade dispensing packages entirely of molded plastic have resulted in containers from which, all too often, more than one blade comes out at a time when only a single blade is desired. The present invention combines the attractive appearance and lower cost of a molded plastic package with a one piece stamped metal tray slidably engageable within a molded plastic sleeve whereby the necessary mechanical tolerances are provided by the metal part. In assembly a stack of razor blades is machine loaded onto the metal tray, the ends of the tray are folded over the ends of the blades, and the machine loader then slides the loaded tray into the plastic sleeve wherein detents formed on the inner sleeve walls kick the tray into position, thereby completing the package.

OBJECTS OF THE INVENTION Accordingly, it is an object of the invention to provide an improved razor blade dispensing package container from which blades may be singly and positively removed by the user without danger of inadvertently cutting his fingers, and without damage to the finely sharpened blade edges.

Another object is to provide such a razor blade package formed of only two parts for simplicity and economy of manufacture and assembly, and entirely. adapted to automatic machine loading. I I

A further object is to provide such a razor blade dispensing container having means for conveniently and safely storing used blades in a compartment separated from the new blades.

An additional object is to provide an inexpensive razor blade dispensing package having all of the above features incorporated in a commercially attractive embodiment.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises an article of manufacture possessing the features, properties, and the relation of elements which will be exemplified in the article hereinafter described, and the scope of the invention will be indicated in the claims.

DETAILED DESCRIPTION Referring now in greater detail to FIG. 1 of the drawings, it will be seen that the razor blade dispensing container of the invention comprises a generally rectangular outer cover member 11 having an elongated opening 12 in the top rectangular surface thereof with a rounded or beveled edge 13. The top razor blade 14 in the package is visible through the opening 12 and access to its top surface by the user's thumb enables a single blade to be dispensed from the end of thepackage as shown in FIG. 1. The blade 14 is dispensed as shown without any occasion forthe users hand to come in contact with the sharp cutting edges of the blade. I

Referring now to FIG. 2, which is a longitudinal cross section view taken along the line 2-2 of FIG. 1, it will be seen that the bottom rectangular surface 15 of the container 11 bass lateral opening 16 formed in'one end thereof into which used razor blades may be inserted for safe storage. The opposite ends 18 and 19 of the assembled and loaded package shown in FIG. 2 are formed by folded metal end portions of a blade holding tray generally indicated at 20. The tray 20 has a horizontally disposed central plateau portion 21 from which are stamped an upwardly biased spring loaded central guide member 22 and a pair of downwardly extending detent members 23-23 as may be seen more clearly in FIG. 3.

Referring now to-FIG. 3, of the drawings, the metal blade holding tray 20 is shown in perspective in condition ready for loading of razor blades therein preparatory for insertion of the tray into the sleeve member 11. From the central portion of the plateau 21 a spring portion 22 is lanced and drawn upwardly forming a vertically extending central guide member 24. The tip of portion 22 serves as a spring member to constantly bias blades in the container upwardly toward the longitudinal opening 12 whereby the top blade 14 is in alinement with a transverse exit slot 35 which is pierced through the top corner of end wall 18, as will be described more fully with reference to FIG. 4. The detent members 23-23 are lanced downwardly below the plane of the plateau 21 as clearly shown in FIGS. 2 and 3. Still referring to FIG. 3, end portions of the tray 20 are folded downwardly about a right angle at 25 and 26 forming downwardly extending parallel portions 27 18 and 19. The extreme opposite ends of the tray, 31 and 32, are then bent at right angles respectively to end walls Band 19 at the points 33 and 34 along lines again parallel to the folds at 29, 30 and 25, 26. At this stage of formatidn the tray 20 is ready to receive a stack of new razor blades which may be dropped by a machine loader directly on to the spring member 22 and center guide 24 of the tray 20. When the stack of blades are dropped onto tray 20 they are centered by member 24 and are held upwardly by the spring member 22 which restrains the bottom of the stack from riding directly upon the surface of the plateau 21. When the blades are thus loaded the end members 18 and 19 are then foldedupwardly about the acute angles at 29 and 30 until they are parallel to and in substantially intimate contact with the downwardly extending end portions 27 and 28, and the top of the blade stack is then clamped beneath the inner ends 31 and 32 of the tray 20, whereby the blades are held securely in the tray.

Referring now to FIG. 4 of the drawings which is an exploded perspective view showing the loaded blade holding tray 20 at the right, ready for insertion into the hollow rectangular sleeve member 11 seen to the left in FIG. 4. The lateral exit slot 35, which is pierced through the top edge of the lefthand end wall 18 adjacentto and including the folded corner 33, is of a length greater than the width of the razorvblades in the stack whereby the top blade 14 (and each successive blade) may pass therethrough without damage to the cutting edges. It is through thisexit slot 35 that blades are dispensed by manipulation'as illustrated in FIG. 1. To assure that only one blade at a time can be passed through slot 35, it is provided with two dimensional determining tabs 36 and 37 which form bearing surfaces over which the bottom surface of the top blade rides during the dispensing operation. The: tabs-36 and 37 are precisely spaced from the upper edge 38 of the slot 35 by a distance d in FIG. 2 which is slightly greater than the thickness of a single blade but substantially less than the thickness of two blades, thus rendering it impossible for more than one blade to be dispensed at a time. As most modern safety razor blades are formed of steel .005 inches thick, the

spacing for the dimension d between the tabs 36and 37. and

the top edge 38 of slot 35 is preferably rnadeto be exactly .006

- inches, (20003). The final step in assembly in the completely -package. A detent 42 in the inner bottom wall surface of plastic sleeve 11 engages the inner bottom end surface 28 whereby the tray is then securely locked and centered within the plastic sleeve 11.

Referring to FIGS. 5 through 12 of 1 the drawings an alternate embodiment of the i'nvention will be described whereby razor blades may be dispensed directly onto the center guide bar of a safety razor without any need for the user to touch any portion of the bladeduring the dispensing and razor loading operation. This may be termed a glider type dispenser because the razor itself enters a narrow slot in the top of the package and hooks onto the top blade which is then drawn out by manipulation of the razor and package jointly as shown in FIG. 10 of the drawings.

Referring now moreparticularly to FIG. '5, a molded plastic sleeve member 50 of substantially rectangular configuration has an end opening 51 as seen at the right and a corresponding open end 51:: to the left. The top surface 52' of sleeve 50 is curved upwardly as appears more clearly in FIG. bhas through 53a and into 57 at 53b. Two lateral exit slots 58 and 59'extend transversely across the ends of slot 53 through the junction between the plane end surfaces 56 and 57 and the-upper curved surface 52. In this embodiment of the invention blades are alternately stagger loaded into the metal tray inserts in such manner that they are alternately dispensed first from exit slot 58, next from exit slot 59, and then back to exit slot 58 again for the next blade.

FIG. 6 shows, in perspective view, the metal tray for supporting razor blades of this embodiment of the invention prior to the loading of blades thereon. The tray 60 has a central plateau portion 61 which corresponds in most respects with the corresponding portion of the tray in FIG. 3 except that the plateau 61 of the tray 60 is somewhat longer than the plateau of the tray 20 in FIG. 3, in order to permit staggered stacking of blades thereon. Two pairs of upwardly biased spring members 62-62 and 63-63 are lanced lanced on opposite sides of the central portion of the plateau 61 for the purpose of supporting blades thereon under spring pressure. A pair of downwardly extending tab members 64-64 are lanced in the right-hand end of the plateau 61 in substantially the same manner as the tabs 23-23 shown in FIG. 3 of the first embodiment. The end walls 65 and 66 of the tray 60 may be formed in exactly the same manner as illustrated and described with reference to FIG. 3 heretofore, or it may be preferred to provide an additional fold under at each end, 67 and 68, as shown in FIG. 6 for the purpose of providing a more secure clamping engagement of the staggered blade ends. A staggered stack of razor blades is now deposited onto the tray 60 of FIG. 6, having their inner ends interleaved and overlapping (as may be seen in FIG. 7) and their outer ends adjacent to the opposite edges of the tray plateau 61. It will be understood that the blades in this stack'do not rest directly on the plateau 61 but instead rest uponand are supportedby the upwardly biased springs 62-62 and 63-63. When the blades have been so deposited in a staggered alternate stack the end members 65 and 66 are then folded inwardly to bring ends 65 and 66 into right angle position with respect to the plateau 61 whereby the opposite ends of alternate blades in the stack are securely clamped between the supporting springs 62-63 and the surfaces 67 and 68 of end members 65 and 66, as is more clearly shown in the perspective view of FIG. 7. When the tray 60 has been fully loaded as shown in FIG. 7, the package assembly is completed by sliding the tray into one of the open ends of the sleeve member 50 shown in FIG. 5. The end 66 of tray 60 as shown in FIG.' 7 must be inserted in the opening of the sleeve 50 and this end may be inserted either in the open end 51 of FIG. 5 or in the opposite end 51a.

, F IG. 8 is a longitudinal vertical cross section of the completely assembled package showing the relation of all parts after the tray 60 has been slid into the lefthand open end Slaof the sleeve member illustrated in FIG. 5. As appears in FIG. 8, the top blade 14 of the stack is spring biased against the-inner surface of the top portion 52 of the molded plastic sleeve member and the free end of blade 14 is alined with exit slot 58 whereby the blade may be dispensed through slot 58 by I the insertion of a central guide bar of an open safety razor central guide bar. When this is done the next blade, 14a,

springs upwardly so that its right-hand end bears against the inner surface'of the top portion 52 and in alinement with exit slot 59. Thus the next dispensing operation will be performed by movement of the razor engaging central guide bar through the slot 53 in the direction from-left to right as viewed in FIG.

8. Successiveblades may be removed alternately from exit slots 58 and 59 until the package is empty.

FIG. 9 is a transverse cross section through the center of the assembled package taken along the line 9-9 of FIG. 8. In FIG. 9 it may be seen that a pair. of longitudinally extending molded plastic ridges 71 and 72 are formed on the underside of the inner top surface 52 to reduce frictional engagement of the top blade with the enclosing package during the removal of a blade therefrom.

As illustrated in FIG. 10, the preferred manner of use of the dispensing razor blade package in this second embodiment is by turning the entire package upside down, or holding it at an angle as shown, and inserting the central guide bar of an opened safety razor into slot 53 near one end of the package, in this illustration at the end 53b, sliding the package across the razor with the central guide bar progressing through the slot 53 until its leading edge engages the central guide slot in the upwardly extending end of the top blade, and continuing this motion until the razors central guide bar exists from the slot 53 whereupon the top blade will be deposited in the razor and the razor may be closed and used in the normal manner without the user ever having to touch any portion of the blade during the loading operation. For this embodiment of the'invention, the razor blades are preferably imprinted with directional arrows 71-71 as shown in FIG. 7. All of the blades in the right-hand portion of the stack shown loaded in FIG. 7 have arrows pointing in the direction of 7l-71, while-the other blades clamped beneath the folded end 65 in the lefthand portion of the tray 60 are marked with arrows in the opposite direction so that the arrows clearly indicate to the user the direction in which the razor should be passed through the slot 53 for proper dispensing and loading of one blade at a time. Preferably in the second embodiment the sleeve member, or at least the top thereof, is formed of transparent plastic so that the directional arrows imprinted on the razor blades may be viewed through the top of the package.

Referring now to FIGS. 11 and 12 of the drawings it will be seen that the second embodiment of the invention may be practiced with a plane flat top sleeve package if desired. In FIG. 11 the top surfaces 72 and 74 of the molded plastic sleeve areformed flat and in the same plane, being separated by a centrally disposed longitudinally extending slot 75 which extends the entire length of the sleeve except for a small bridge portion 76 which is in in the middle of slot 75 to provide rigidity and mechanical strength for the assembled package. The structural design of FIG. 11 provides a narrow space, which may be of the order of .008 inch to .012+ inch, between the upper end surface 77--78 of the metal insert member and the inner top surfaces 79-80 of the molded plastic sleeve, as may be seen more clearly in the end view of FIG. 12.

Referring now in greater detail to FIG. 12 of the drawings, a pair of longitudinally extending corner guides 81 and 82 are formed in the upper insidecomer edges of the molded plastic sleeve 85 adjoining the-inner top surfaces 80 and 79 respectively. The top surfaces 77 and 78 of the metal tray insert bear against and ride under the comet guides 81 and 82 thereby forming. between the metal surfaces 77-78 and the inner plastic sleeve surfaces 79 -80 transverse blade exitports 83 and 84 at opposite ends of the assembled package illustrated in FIGS. 11 and, 12. The vertical dimensions of the exit ports 83 and 84 in this embodiment of the invention are notcritical because the blades are alternately dispensed from opposite ends of the staggered stack, and the inherent springiness of the curved blades in the compressed stack causes the top blade to bear against the inner top surfaces 79 and 80 in alinement with only one of the exit ports. In this second embodiment of the invention, as illustrated by'FIGS. 5 through 12, it is virtually impossible to remove a second blade from the package until the top blade has first been removed. Accordingly the exit ports 83-84 in FIGS. 11 and 12, and corresponding exit ports 58- -59 in FIGS. 5, 8 and 10, are formed to a noncritical dimension which may vary from .008 inch to .012+ inch.

It will thus beseen that the objects set forth above, among those made apparent from the preceding description, are effieiently attained and, since certain changes may be made in the above product without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
